Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloyed with magnesium for strength
Mg-alloyed profiles for structural use classify under 7604.29 other alloys.
If imported as complete greenhouse kits
Prefabricated greenhouse structures with profiles classify as prefabricated buildings.
If rolled into thinner plates post-extrusion
Plate/sheet forms from same material shift to Chapter 76 rolled products.

Import Tips & Compliance
• Use spectrographic analysis reports to prove <99.1% purity threshold compliance
• Ensure no surface treatments like anodizing, which could shift to 7616.99
• Bulk coil imports risk confusion with wire—specify straight lengths >6m
